A method for removing deposits from at least one compressor powered by an engine. The method comprises disconnecting while the engine is turned off, a high pressure downstream side of the compressor from an intercooler, or an air intake manifold for non-intercooled engines, while leaving the compressor attached to a means used in the engine to drive the compressor. The output airflow is diverted from the compressor away from the engine to a disposal or to a means of separating a cleaning fluid from air. After starting the engine and while the engine is running, the cleaning fluid is injected for a sufficient time to clean the compressor.

1. A method for removing deposits from at least one compressor powered and used by a compression ignition engine, comprising (a) disconnecting, while said engine is turned off, a high pressure downstream side outlet of said compressor from an intercooler of the engine, or an air intake manifold for non-intercooled engines, while leaving said compressor attached to the engine to drive the compressor, (b) diverting the output airflow from said compressor away from the engine to a receptacle for separating a cleaning fluid from air, (c) starting said engine, (d) introducing an injector to inject said cleaning fluid into an air stream in a low pressure side upstream of said compressor; and (e) while said engine is running, injecting said cleaning fluid via the injector in step (d) for a sufficient time to clean said compressor. 2. The method of claim 1 wherein said cleaning fluid comprises (i) a major amount of an aromatic hydrocarbon solvent. 3. The method of claim 2, wherein said cleaning fluid further comprises (i) at least one nitrogen containing detergent additive. 4. The method of claim 2 wherein said aromatic hydrocarbon, solvent comprises a C9 aromatic solvent. 5. The method of claim 2 wherein said aromatic-hydrocarbon solvent comprises at least 80 volume percent aromatics. 6. The method of claim 2 wherein said aromatic hydrocarbon solvent comprises at least 90 volume percent aromatics. 7. The method of claim 1 wherein said receptacle for separating said cleaning fluid from air in step (b) is a fluid separation drum. 8. The method of claim 3 wherein said at least one nitrogen containing detergent additive comprises a hydrocarbyl-substituted succinimide. 9. The method of claim 1 wherein said compressor is a turbocharger compressor. 10. The method of claim 1 wherein said compressor is a supercharger compressor. 11. A method for removing deposits from at least one compressor powered and used by a compression ignition engine, comprising (a) disconnecting, while said engine is turned off, a high pressure downstream side outlet of said compressor from an intercooler for the engine, or an air intake manifold for non-intercooled engines, while leaving said compressor attached to the engine to drive the compressor, (b) attaching a conduit to the high pressure downstream side outlet of said compressor, (c) attaching, an input to and output from, a receptacle for separating a cleaning fluid from air, (d) diverting the output airflow from said compressor to said receptacle for separating said cleaning fluid from air, and further directing the remainder of said airflow to said engine, (e) starting said engine (f) introducing an injector to inject said cleaning fluid into an air stream in a low pressure side upstream of said compressor; and (g) while said engine is running, injecting said cleaning fluid via the injector in step (f), for a sufficient time to clean said compressor. 12. The method of claim 11, wherein said cleaning fluid comprises (i) a major amount of an aromatic hydrocarbon solvent. 13. The method of claim 12, wherein said cleaning fluid further comprises (i) at least one nitrogen containing detergent additive. 14. The method of claim 12 wherein said aromatic hydrocarbon solvent comprises a C9 aromatic solvent. 15. The method of claim 12 wherein said aromatic hydrocarbon solvent comprises at least 80 volume percent aromatics. 16. The method of claim 12 wherein said aromatic hydrocarbon solvent comprises at least 9.0 volume percent aromatics. 17. The method of claim 11 wherein said receptacle for separating said cleaning fluid from air in step (c) is a fluid separation drum. 18. The method of claim 13 wherein said at least one nitrogen containing detergent additive comprises a hydrocarbyl-substituted succinimide. 19. The method of claim 11 wherein said compressor is a turbocharger compressor. 20. The method of claim 11 wherein said compressor is a supercharger compressor.
